Alguém me ajuda ?
​

Answer 1

A)

5 + 3x= - 1 + 4x

3x - 4x= - 1 - 5

- 1x= - 6

x= -6/ -1

x= 6

B)

- 15 - 11x= - 9 - 3x

- 11x + 3x= - 9 + 15

- 8x= 6

x= 6/ -8

C)

- 4= 2 - 3x

3x= 2 + 4

3x= 6

x= 6/ 3

x= 2

D)

5 - 2x= - 17

- 2x= - 17 - 5

- 2x= - 22

x= -22/ -2

x= 11

Answer 2

a)5+3x=-1+4x

3x-4x=-1-5

x=-4

b)-15-11x=-9-3x

-11x+3x=-9+15

-8x=-6

x=-6/8

c)-4=2-3x

3x=2+4

3x=6

x=6/3

x=2

d)5-2x=-17

-2x=-17-5

-2x=-22

x=-22/2

x=-11
